This invention relates to hose cou Hugs, and articularl to that class descri d as quic y detacha le hose couplings.

The object of this invention is to provide a coupling for hoses'carrying water, oil, air or other substance under pressure, and'to effect therefore a hermetic seal, combining with this accomplishment positive action an ra idity of operation.

n the accompanying drawin? Figure 1 "is a view of the coupling engage Figure 2 is a sectional view of the same on the line 2-2 of Figure 1.

Fi re 3 is a view in side elevation showingt e couplin turned a quarter turn from the position in icated in Figure 1.

Figure 4 is a top plan view of one of the coupling members taken in the directionof the arrow 4 upon Figure 5.

Figure 5 is a view in side elevation showing one member of the coupling termed the male member.

Figure 6 is a view in side elevation of the other, or female member of the couplin Figure 7 is a top plan view of the fema e member taken in the direction of the arrow 6 upon Figure 5.

on by suitable clamping arrangement.

' comprises a cylindrical bod Formed integrally with the hollow cylindrical body is an enlar ed annular shoulder 4 which is knurled to acilitate gripping 1t.

Upon the opposite side of the shoulder 4 from the body 1 there is formed a cylindrical portion 8, upon the opposite sides of which are formed upwardly inclined shoulders 5 terminating in tongues or clasps 6 which extend over recesses 7. The tongues 7 'are adapted to engage with tongues upon the female member hereinafter described. The cylindrical portion 8 is adapted to telescope with the female member as shown in Figure 2 and has a flat upper edge 9, upon which is adapted to rest a washer 10 when the male and female members are in assembled relation. v

A female member illustrated in Figure 6 12 similar to the cylindricalbody 1, to which is clamped hose 13, a knurled nut 14, and eripheral diagonally disposed tongues or c as s 15, these latter being adapted to occupy t e recesses '15 exten 7 and enga been properly clasped and occ zgy the shoul-,

der recesses the resiliency of e Washer 10 offering suiiicient resistance to actively retain the opposing members in locked engagement.

It will be noted that when this coupling has been accom lished the body continuation 18 will fit tight y within the shoulder 5 and the cylindrical portion 8, andthe hollow shoulder 16 will be in frictional proximity with the outside of the shoulder 8 thus effecting a positive coupling and effective seal, permittlng a flow 0 liquid through the channel 20.

In the modified form of my invention as illustrated in Fi 8 and 9. The illustration shows a ma e member which may take the place of that shown in Fig. 5 and be connected to the socket member such as shown in Fig. 6. In this case the pins 21 and 22 engage behind the tongues 15 similar to a bayonet ty e connection with the cylindrical body to w ich the pins are secured extending into the annular space between the elongated shoulder 16 and the continuation 18 of the cylindrical body 12, a' packing washer similar to 10 being used to seal the joint.

It W111 be understood that various changes may be made in the details of the construction without departing from the spirit or scope of the invention as defined in the appending claim.

I claim:

A hose coupling comprisin a male couphng member with a cylindrical body 1 adapted to receive a hose, a cylindrical ortion 8 at the other end of the coupling I ia mg a flat upper end 9, an annular recess forming a soc et on the inside of the cylindrical portion having an abutment at its inner end, oppositel inclined shoulders 5 integral with the cylindrical portion and on the outside thereof, tongues 6 terminating at the shoulders and forming recesses 7 theretongues 15 on the ends of the shoulders 16 under in combination with a female member forinin recesses thereunder, the tongues on having a cylindrical portion 12 adapted to the ma e and female members fitting in the receive a hose, a continuation 18 at the other respective recesses under the tongues and 5 end of the cylindrical body adapted to fit a washer 10 bearing on the flat end 9 and the 15 in the socket formed by the annular recess annular wall of the groove 17. on the inside of the cylindrical portion 8 o In testimony whereof I have signed my the male member, integral elongated shoulname to this specification. dcrs 16 forming an annular groove 17 be- 10 tween said shoulders 16 and continuation 18, J. J. HEINRICH.
